Description
Technical field
The utility model relates to the rotary kiln field that produces lime, relates in particular to frictional drive lime rotary kiln in a kind of self-regulated.
Background technology
Rotary kiln lime calcining has had 300 years above history, and in China, from since the technology and equipment of 20 century 70 equipment Imported From German EMH Companies and the U.S., shaft preheater, shaft cooler are promoted widely.At present, on-stream and newly-built lime rotary kiln adopts shaft preheater and cooler technology more, and the preheating of lime stone and a part of decomposition reaction are all carried out in preheater, and the length of rotary kiln is further shortened.The draw ratio of modern lime rotary kiln is all in 1:15.Therefore newly-designed lime rotary kiln is all two groups of support roller supportings that adopt, and this makes to adopt friction mode to carry out transmitting torque between support roller and rolling ring becomes possibility.
That the quality of evaluating the design of rotary kiln mainly contains is easy to operate, maintenance cost is low, also has these three of costs of use (being mainly that power consumption is low).Modern lime rotary kiln output is increasing, and diameter is also increasing.Such as, the lime rotary kiln diameter of 1200 tons/day has reached 5.2m.Due to above factor, the contact stress between support roller and the rolling ring of lime rotary kiln is also increasing.The drawback of fixed like this support roller technology is also just more and more obvious.Axis between two groups of corresponding axis of support roller and cylinder of rotary kiln in fixed wheel holding mechanism is to adjust by the jackscrew after supporting-roller shaft bearing, and heart position is only had to one in theory.In practical operation, be difficult to accomplish that two axis are completely parallel, even if it is parallel that two axis are adjusted when cold conditions, but the temperature that two groups of support rollers support corresponding position when hot is different, and Temperature Difference Ratio is larger, the diameter of kiln is also very large simultaneously, exist larger thermal expansion amount poor, this just causes drive current and the theoretical value of now a lot of kiln kilns when cold conditions very approaching, drive current and theoretical value are aborning far short of what is expected, are mainly because two axis are no longer parallel when hot.
Now some design, artificial reduces the height of high temperature section supporting arrangement according to calculating suitably, make two axial lines when hot be tending towards theoretical value, does like this and can play a role.But when the damage of refractory material in kiln, in kiln, the variation of each several part temperature can directly have influence on the theoretical value of this calculating, and then has influence on the effect of artificial adjustment.The axis of the determined axis of support roller group and kiln cylinder body misaligns the impact causing and mainly contains: the one, and kiln running needs larger power, causes driving power to consume excessive, and the operating cost of kiln increases; The 2nd, between support roller and rolling ring, be no longer linear contact, reduce the service life of support roller and rolling ring, once need maintenance, kiln is cooling very large to the damage of refractory material in kiln, these have all increased the maintenance cost of kiln.
Summary of the invention
The purpose of this utility model is to provide frictional drive lime rotary kiln in a kind of self-regulated, with self-aligning function, by the frictional force between support roller and rolling ring, transmit driving torque, reduction is because of rotary kiln axis and the not parallel contact stress producing of the determined axis of support roller group, extend the service life of kiln body rolling ring, reduce maintenance cost and the operating cost of rotary kiln.
For achieving the above object, the utility model is achieved through the following technical solutions:
Frictional drive lime rotary kiln in self-regulated, comprise active roller station group, driven support roller group, kiln body and rolling ring, under kiln body, be respectively equipped with active roller station group and driven support roller group, wherein active roller station group matches with the rolling ring that is positioned at kiln body feed side, described driven support roller group comprises that structure is identical, two riding wheel apparatus that are arranged symmetrically with, the opposite side of two riding wheel apparatus is hinged with the two ends of central substrate respectively, the below, opposite side bottom of two riding wheel apparatus is respectively equipped with hinge beam, between riding wheel apparatus and hinge beam, be provided with resilient rubbber cushion, when driven support roller group contacts with rolling ring, central substrate is in quick condition.
Described resilient rubbber cushion is two two ends that are separately positioned on a hinge beam.
The base of the bottom of described hinge beam and kiln body is hinged.
The bottom of described riding wheel apparatus is provided with the positive stop of restriction hinge beam amplitude of fluctuation.
In described active roller station group, be also provided with and two riding wheel apparatus identical in driven support roller group, direct-connected on one group of riding wheel apparatus therein have a planet cycloid speed reducer, described planet cycloid speed reducer is furnished with self adaptation base and is fixed on fixing basis, the primary input end of planet cycloid speed reducer is connected with main motor through Hooks coupling universal coupling, being connected with dish kiln motor through freewheel clutch from input of planet cycloid speed reducer.
Compared with prior art, the beneficial effects of the utility model are:
1) make the determined axis of support roller group and the automatic centering of kiln body rolling ring axis, avoid the excessive wear of support roller and rolling ring, improved the service life of support roller and rolling ring.2) improve rotary kiln quantity-produced ability, reduced widely the maintenance cost of kiln body.3) driving power while having reduced rotary kiln running, thus the operating cost of rotary kiln reduced.4) cancelled the parts such as bull gear, pinion, the parts of rotary kiln are further reduced, made transmission mechanism compacter, reduced maintenance workload, also reduced the construction volume of concrete foundation, thereby be minimized cost of investment simultaneously.
